Wire Interlocks
The ORS SITEPRO™ 2000 has four
intrinsically safe and four non-intrinsically safe interlock inputs available for
attachment of external interlock devices to the panel alarm channels. Geotech suggests that a maximum of two
interlocks be wired to a channel, when two interlocks are wired to the same channel, both must be wired either Normally
Open , or Normally Closed. If both switches are wired normally closed, however, both switches must open for the panel
to respond with an alarm on that Interlock channel.
To shut off an optional feed pump in the event of a High Sump Level or High/Low
Pressure condition, the inputs for each of these functions must be jumpered to an
alarm channel as explained in Appendix D: Application Notes.
Never wire both a Normally Open and a Normally closed interlock device to the same
channel. Doing so could cause the panel to either lock in alarm or be unable to read an
alarm.
